The hearted tattoo on her finger isn't real,it's fake....
It's real because they wanted to cover it up in Violetta 3. :)
Martina has 3 tattoos. If you look on mostly pics from Violetta 3 and Violetta en Vivo, you can see that they're covering them.
3??? I thought it was 2. One in her wrist, and another in her neck. Where's another one?
